Controlling Classroom Temperature Discussed for Local Committee
Controlling the temnerahiro In
a classroom has been a problem
for many years.
. Often times during the winter
months, when heating systems
are operating to near capacity,
classroom windows are open to
provide better circulation of air.
The same windows are open
during the warmer months for
better circulation, although the
air being circulated may not be
cool.
This situation, however, may
be eliminated in future construc
tion of classrooms with the more
refined development and in
creasing use of the heat pump.
Basically, tne neat pump is
a compressor, similar to tne
type in the regular refrigerator.

which rpmnves rnol or warrr !
air from a given area. For ex
ample, if a room needs heat,
the unit takes warmth from the
outside air and circulates it in
the room; if the room needs to
be cooled, warm air is extracted
from the room.
Costs More Reasonable
Although not new, installation
of a heat pump system of heat
ing and cooling lias been quite
expensive until more recent
vears. Installation costs a r c I
now more reasonable, and heat
pumps have been installed in
many commercial buildings.
But only in more recent years
has the heat pump been used
in school plants. In Oregon, in
creased use of the heat pump
in public schools has been chief
ly the result of the work of
Chester V. Jarrett, manager of
public services, Portland, Gen
eral Electric company, Port
land. Jarrett discussed heating and
cooling systems at a meeting of
the Medford school district's
Citizens' Advisory Committee
last week.
Controlling the Temperature
He pointed out the importance
of controlling the temperature
of the classroom for more effi
cient learning.
Other reasons for controlling
classroom temperatures were
outlined by Delos Williams, as
sistant state superintendent of
public instruction in charge of
schoolhouse planning.
Williams pointed out that with
controlled temperatures, better
attendance was noted, fewer
disciplinary problems were not
ed, and the amount of illness
was reduced. Whether a stu
dent's achievement is higher in
a controlled climate room has
not yet been proven, Williams
said, but indications are strong
that achievement is higher.
Jarrett. in cooperation with
six school districts in the Port
land area, conducted a research
project involving heating and
cooling classrooms. Various
types of heating systems and
heat pump systems were in
stalled, along with equipment
to record temperature ranges,
both inside and outside, t h e
leneth nf time the unit hnntnrl '
Cooled More Than Heated I
Charts drawn up from data ;
gathered from the schools show- '
ed that most classrooms were
cooled more than they were
heated. Rooms were heated dur
ing the early morning hours,
but after students arrived, and
heat was generated from the
sun and students, the heat
pump automatically started
cooling the rooms.
Jarrett pointed out that a
classroom can be pre-heated be-!
fore class starts when the tern
perature outside is zero degrees
Fahrenheit. !
After class starts in the room, :
it will require no more heat
during the day because of the
net gain in heat from the stu
dents, the sky and sun, and
lights, Jarrett said. In fact, to
hold the room temperature
relatively even, the room will
need to be cooled, even as the
temperature outside remains
low. . !
This is borne out in data col
lected in the six schools coop
erating in the research project. '
Both work at unce
Jarrett said that in many
cases one or more rooms in a
school may be heated at the
same time other rooms are :
being cooled. This was the case
in some of the research schools
in which the climate was con-
trolled by individual heat pumps
for each classroom.
Cost of installation of a heat-,
ing - cooling system is actually ;
no greater when the units are
put in during construction of
new buildings, Jarrett noted. .
Changes in the construction I
plans can be made to offset the j
additional cost of the heat pump
unit.
Operating costs, with a heat
ing - cooling unit, are reason
able, the research project show
ed. Operating costs were com
piled on the basis of cost per
square foot, and ranged from
14.128 cents at Estacada High
school, which had only heating
units, to 3.7 cents at the new
Mifwaukie High school for heat
ing and cooling.
Learning Efficiency
Jarrett pointed out that the
concern is not so much whether
a student is comfortable as it
whether the student's learn-
efficiency decreases when
,ie is uncomfortable.
A student's learning efficiency
does drop when uncomfortable,
but educators are not sure just
how much. The range of loss of
efficiency has been estimated
between 15 and 60 per cent, de
pending upon conditions.
Jarrett used a figure of 10
per cent drop in efficiency as
a basis for his research. Follow
ing this through, if it costs $450
per year per student in high
school, and the student is un
comfortable 57 per cent of the
time, $30 of the cost of educating
the student has been wasted.
No valuation can be placed on
the amount of learning the stu
dent has lost for life, Jarrett
noted.
Provide Comfortable Room
Providing a comfortable room
through cooling would cost less
than $5 per student per year, he
noted; comparing this to the
conservative cost of loss of
learning efficiency, the cost of
air conditioning is $25 less on
a per pupil basis.
Jarrett also mentioned that
the extended school year that
is, classroom use throughout the
12 months rather than just nine
should also be considered
when new school plants are dis
cussed. He said school adminis
trators in the not too distant fu
ture will face the question of
using the school plant through
out the year.
He pointed out that air condi
tioning of schools today is eco
nomically feasible as well as
warranted from the standpoint
of providing the best environ
ment for learning.

Extension of Road
Opens for Traffic
Highland dr. extension was
opened In vehicle traffic
Wednesday when contractor's
crews finished installation of
asphalt paving, according to
Vernon Thorpe, Medford public
works director.
The street extension project
was designed to provide easy
access between East Main st.
and Barnett rd. The major con
tractor for the project was M. C.
Lininger and Sons. Total cost
was $28,000.
Thorpe also announced com
pletion of paving work on Siski
you blvd. Except for a l.ooo
foot section in the center which
was covered with an oil mat,
the paving extends from 10th
st. to Willamette ave. M. C.
Lininger and Sons also was
contractor for the project.
